What the tradition reads

The ascendant, also called the rising sign or lagna, is the degree of the zodiac standing on the eastern horizon at the exact moment and place of birth, and both major traditions treat it as the single most personal point in the whole chart, more particular to that instant than any planet. In the Western system it marks the cusp of the first house and, with the Midheaven, fixes every other house cusp that follows from it; the astrologers read it as the face shown to the world, the manner of first appearance, and the lens through which the rest of the chart's contents are expressed outward. In the Vedic system the lagna performs the same office for the whole sign bhava chakra, since every house from the first onward is counted as a full sign forward from whichever sign the ascendant occupies, so the lagna sign and its ruling planet are read as governing the native's constitution and general fortune more broadly than in the Western reading. Because the ascendant moves roughly one degree every four minutes, it is the value in a chart most sensitive to an uncertain birth time, and both traditions treat a chart with a doubtful ascendant as unreliable for house based judgement even where the planets' signs are secure.

The story

The Greek term behind the ascendant is horoskopos, glossed by Wikipedia's page as "hour marker," and Wiktionary's entry for horoscope traces the word to hora, meaning any limited time, and skopos, a watcher. Babylonian astronomers already tracked the rising times of the zodiacal signs, without leaving behind a word that survives as "ascendant" itself, and by the third century BCE Egyptians read the rising of specific star groups to identify the ascending sign and judge the time of night, the habit Wikipedia's page connects to the Greek name that followed. The Greek manuscript of Ptolemy's Tetrabiblos itself uses horoskopos for the ascendant and horoskopia for observation of the ascendant, though Ashmand's own English translation renders the word plainly as "horoscope," as when it calls the rising sign "the sign ascending (which is also called the horoscope)." The astrologer Balbilus is credited with the first documented mention of an ascendant applied to an actual nativity. From this word "horoscope" eventually came to mean the whole birth chart in English, even though its Greek root names only the single rising degree the chart is built around, the point later languages softened into "ascendant," which Wiktionary traces to the Latin ascendens, rising, from ascendere, to climb or go up.
